ZHA worked well for me with Conbee II and the Lidl power socket, LED strip and bulbs. For the Xiaomi stuff it’s worked well with the Temp/Humidity & Motion (PIR) sensor.
ZHA works well for me with ZZH and all the above plus the Door/Window sensor.
I can’t comment on the Blitzwolf/Osram products or Hue.
Thanks for the feedback @mandelbug . So you haven’t tested the Door/Window sensor with the Conbee II and ZHA? (I assume it shouldn’t make a difference with the coordinator)
Do you find that the ZZH is better than the Conbee II?
Correct, I haven’t connected the Door/Window Sensors via Conbee II to ZHA. They are connected via ZZH. I can’t see it being an issue though to be fair.
I am not 100% sure how much of a difference there is between the two. I still use the Conbee II as I have an IKEA FYRTUR blind which doesn’t work so well with the ZZH (I can’t find the GitHub where it mentioned using a broadcast message) I am using V3 firmware with the ZZH. Certainly no complaints with performance of devices, they respond fast when asking them to switch on etc
